By default StationPro only uses one sidebar. You'll need some CSS customization to add the second sidebar. One way to do that is by creating a child theme based on StationPro and editing one of the files there to add the other sidebar. More on child themes can be found here: http://codex.wordpre...rg/Child_Themes

I'm not a developer/experienced enough with PHP so I'm not so certain I'd be the right person to do this, but perhaps you can get in touch with someone else who would be happy to do this for you. Try e-mailing hello@pagelines.com for a request.
